GeoID1.80 - App Store

* Note : This app uses built-in magnetometer, so iPod Touch does not provides direction of structure/device.

GeoID is a professional tool for measuring and analyzing geological structures. This application includes geological compass, stereographic projection, instability analysis and wireless data sharing.

. Features
- The clinometer works with all attitude of the device and enables user to measure any structure
- A stability indicator in the clinometer maximizes its accuracy
- Provides many options including notation type, measurement interval, avarage calculation, projection type, etc.
- Can input data manually using several input methods
- Immediate projection and analysis of selected project
- Provides stereonet-based slope stability analysis
- Supports zooming while plotting/analyzing
- Wireless data transferring via Bluetooth and E-mail
- Generates analysis reports with stereonet images and sends them by e-mail
- Supports all iOS devices

Prof. Hyeong Dong Park wishes to express thanks to Prof. Edward Keller and other faculty members of the Earth Sciences Department of University of California Santa Barbara for the useful suggestions and discussions on the improvement of GeoID during Prof. Park's academic visit from 2011-2013.

Version History iOS 8 compatibility and bug fix. 1.80 10/29/2014 Minor bug fix. 1.71 06/13/2013 - Supports iPhone 5 and iOS 6.
- Manual input utility accepts decimals. The numbers are expressed as integers but they contains information below decimal point.
- Instability analyses can be performed on any projection methods.
- Can input variables for instability analysis using keypad.
- Exported files can be e-mailed with all photos on iPhone.
- A project can be e-mailed with photos using E-mail utility on iPhone.
- Fixed a problem that decreases precision of latitude/longitude while sending project wirelessly. 1.70 02/02/2013 - The clinometer will beep differently if the device is "Unstable".
- Records lat/long coordinates to 8 decimal places.
- Minor bugs fixed 1.62 09/28/2012 - Exported file now contains image's name correctly. 1.61 09/01/2012 - Strike/Dip expression follows right-hand rule (looking to the strike of a structure, it dips to the right). You don't have to follow this convention while recording manually.
- Strike/Dip notation has been added to the manual input function.
- Beep-function has also been added to the iPad version.

Thank you for using GeoID.

* Photos are not transmitted via wireless sharing module. 1.5 03/23/2012 - iPad support. 1.4 09/16/2011 - Increased stability
- Minor bug fixes 1.3 09/12/2011 - Structures on stereogram show their orientations in response to touch.
- 'Manual input' mode includes more structural options such as a plane containing two lines, a lineation formed by the intersection of two planes, etc. 1.2 06/27/2011 • Clinometer
- Fixed the default updating interval(0.10s).
- Magnetic sensor calibration message will be appeared when interference is occurred.
• Plot & Analysis
- Added buttons for scrolling the option panel.
- Provides text report of plotted(and analyzed) data. It can be exported to a text file or sent by E-mail including a picture of the stereographic projection.
• Data Sharing
- Provides a new function that exports all projects to a file(TXT or CSV format).
• Misc
- You can access the raw database and exported files using iTunes. 1.1 05/25/2011 1.0 05/18/2011
